We’ve just finished updating our iPhone OS 4 app breakdown article with tons of new screenshots showing off the major accessibility changes in the new software. Notably, iPhone OS 4 offers a new feature called Large Text, which lets users radically increase the size of text in alerts, Calendar, Contacts, Mail, Messages, and Notes, as well as support for Braille device connection, found in the VoiceOver menu. Also found in the VoiceOver settings is support for VoiceOver Phonetics and Pitch Change, which are new to the iPhone and iPod touch but were previously found on the iPad. For more on these and other changes coming in iPhone OS 4, see our full article.
